BY mw Patented Aug. 16, 1938 UNHTED STATES PATENT OFFICE 2 Claims.

This invention relates to improvements in wringers and is directed moreparticularly to wringer heads for supporting and driving wringers.

The principal objects of the invention are the provision of a wringerhead which is not only simple in form and constitutes but acomparatively few parts but which is efficient in its operation. Byreason of the simplicity of the wringer head of the invention it iseconomical to manufacture and so that it is possible to meet with thepresent day demands for low cost apparatus of this type. The wringerhead is of novel form to facilitate ready assembling of the parts whichcontributes to its low cost of production.

Various novel features and advantages of the invention will behereinafter more fully referred to in connection with the accompanyingdescription of the present preferred form thereof, reference being hadto the accompanying drawing wherein Fig. l is a side elevational view ofa wringer head embodying the novel features of the invention;

Fig. 2 is an end elevational view of the wringer head shown in Fig. l;

Fig. 3 is a longitudinal sectional view through the wringer head shownin Fig. 1; and

Fig. 4 is a fragmentary plan view on the line 4 4 of Fig. 3.

Referring now to the drawing more in detail the invention will be fullydescribed.

The wringer head includes a casing 2 which has an upper horizontallydisposed hollow tubular part 4 and a lower vertically disposed tubularpart 6. The lower tubular part 6 has a flange 8 for resting on a columnwhich is usually associated with a washing machine and IG indicates adriving shaft which is usually associated with a washing machine and isdriven by the mechanism thereof. There may be bearings such as I2 forthe shaft I0 in the lower tubular part 6. This shaft I6 on its upper endcarries a driver I4 which in the form of the invention shown is a spurgear.

A detent I6 associated with the part 6 for sliding movements is springpressed downwardly by means of a spring I8, A grip part 20 is associatedwith the detent I6 to facilitate moving it upwardly. The detent is usedto lock the head in various positions on the column referred to.

A pair of spaced driven gears 22 are associated with-a driven shaft 24as by pins 26 so that the gears are non-rotatable relative to the saidshaft. The gears 22 shown as being of the face gear type (Cl. 'i4-337.5)

have teeth 28 on adjacent faces. A collarv or a hub 3U is disposedbetween the gears and in this the shaft 24 rotates. Because the gearshave no peripheral or radially extending teeth, as with a spur or bevelgear they have a smooth periphery and are adapted to rotate and slide ina bore 32 of the head. According to the modification of the inventionshown, one only of the gears rotates and slides in the bore 32 which isenlarged to the right of the left hand gear 22.

A bushing or sleeve 34 is rotatable in a bearing 36 of the head and thisis provided with one or more keyways or splines 36 which receive a pin24 of shaft 24. The shaft and gears slide back and forth so that one orthe other of the gears may be brought into engagement with the driverI4. The key 24 slides in the keyways 36 of bushing 34 provided therefor.The bushing 34 is at al1 times driven however by the shaft 24 and it mayreceive one end of the shaft of the roll of a Wringer.

A shifter 4U carries a bolt 42 which has its lower end screwed intocollar 30. There is an angularly disposed slot 44 in the upper side ofthe head and a bushing 46 around the bolt slides in said angularlydisposed slot.

The member 40 is tilted from the neutral position shown to an angularposition with respect thereto and at either side of the neutralposition. As it is tilted from said neutral position the bushing 46traverses the slot 44 associated with the casing so that the collar ismoved longitudinally and thereby moves the gears longitudinally so thatone or the other of them, depending upon the direction of movement ofthe part 40 is brought into engagement with the driving gear I4.

A detent 50 in member 40 preferably in the form of a ball is presseddownwardly by means of a spring 52 and it is adapted to register with arecess 54 in the upper side of the casing so that when the member 40 isin a certain position it is yieldingly held therein.

It will be observed that one end of the shaft 24 is guided in the member34 while its other end associate-d with the outermost gear 22 issupported by said gear which is rotatable and slidable in the bore 32.This makes for economy in that the usual outer bearing for the shaft 24is eliminated and thereby reduces the manufacturing cost.

The end of bore 32 is closed by a cap 9 which has a flange I l fittingwithin the said bore 32 and is arranged for a tight fit at the end.

In assembling the parts and before the shaft I0 and I4 are assembledwith the head the shaft 24, collar 36 and gears 22 are slipped forwardlyinto the bore 32 and then the screw 42 of the operating member 40 isscrewed into the collar the bushing 46 being around the bolt and in theslot 44. In this way the parts are easily and quickly assembled and thegears and shaft together with the collar as a unit may be removed forreplacement without any great amount of disassembling.

Side flanges 60 on the forward side of the head are provided which mayhave holes 62 therein for securing a wringer to the wringer head.

While I have described the invention in great detail and with respect toa preferred form thereof, it is not desired to be limited thereto sincemany changes and modifications may be made therein without departingfrom the spirit and scope of the invention. What it is desired to claimand secure by Letters Patent of the United States is:

1. A wringer head comprising in combination, a casing having acylindrical outer side, engageable driving and driven gears in thecasing, an oscillatable and reciprocable shiftable member in the casingfor engaging and disengaging saidy gears, the said casing being providedwith a slot in a wall thereof disposed angularly relative to the axis ofreciprocation of the shiftable member, a manually engageable shiftermember radially extending from the casing having curving parts atopposite sides thereof guided on the casing, and a connector betweensaid shifter member extending through the slot in the casing, alladapted and arranged whereby as the shifter member is oscillated it andthe shiftable member are reciprocated.

2. A Wringer head comprising in combination,

a casing having a bore andan outer part of the in alignment with theaxis of said bore, parts at p opposite sides of the manually engageablepart of the shifter engaging the curved outer part of the casing, aconnector between the shifter and shiftable memberextendingthrough saidslot, the outer curved part of the casing provided with a recess,--

and a spring-pressed detent associated with the shiftable memberreceivable in said recess.
